2. 1. Solution-Chemically Derived Spectrally Selective Solar Absorbers : With System Perspectives on Solar Heating

   Author : Tobias Boström; Ewa Wäckelgård; Gunnar Westin; Björn Karlsson; Peter Lund; Uppsala universitet; []
   Keywords : Materials science; solar; thermal; absorber; selective; chemical; Materialvetenskap;

   Abstract : This thesis consists of two parts, one dominating part concerning spectrally selective solar absorbers and one dealing with thermal solar systems. The appended papers I to VIII concern the solar absorber part, papers dealing with the systems part have not been included in the thesis. READ MORE

4. 2. Characterization of selective solar absorbers : Experimental and theoretical modeling

   Author : Tuquabo Tesfamichael; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Abstract : This thesis deals with the preparation, optical characterization and analyses of experimental work and theoretical modeling on selective solar absorbers used in solar thermal collectors. The overall goal has been to obtain efficient absorbers by optimizing the optical properties, and to improve their durability using cost-effective techniques. READ MORE

5. 3. Preparation and Characterization of Sputter Deposited Spectrally Selective Solar Absorbers

   Author : Kristina Gelin; Ewa Wäckelgård; Arne Roos; Björn Karlsson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; spectrally selective solar absorber; thermal emittance; solar absorptance; sputter deposition; infrared reflectance; Teknisk fysik; Engineering physics; Teknisk fysik;

   Abstract : The optical efficiency of a commercially available sputter deposited spectrally selective solar absorber was improved. The main purposes were to decrease the thermal emittance, increase the solar absorbtance of the absorber and to protect the substrate from degradation due to environmental influence. READ MORE

6. 4. Spectrally Selective Solar Absorbing Coatings Prepared by dc Magnetron Sputtering

   Author : Shuxi Zhao; Ewa Wäckelgård; Carl-Gustaf Ribbing; Volker Wittwer; Uppsala universitet; []
   Keywords : Materials science; spectrally selective surface; solar energy; magnetron sputtering; thin film; Materialvetenskap;

   Abstract : Spectrally selective solar absorber using composite Ni-NiO as coating materials was studied. Samples were prepared by dc magnetron sputtering unit named Rulle, which is a miniature copy of an industrial roll-coater unit. READ MORE
